Description

Arguments

default_onscreen	default label to use for a look onscreen that does not fall into an AOI. Default is "tracked"

Details

The function current assumes the conventions used in our lab. It will create a column called GazeByAOI with the label of the AOI for each look. It does this by checking whether the columns XMean and YMean fall into to the boundaries of the AOI.

Offscreen looks receive NA.
